RAY H. IVIGIALWAIN, OF JACKSON, MINNESOTA.

END-GATE CONSTRUCTION.

Application filed October 16, 1924,

Q 10 all whom t may concern:

Be it known that I, RAY H. MCIALWAIN, a citizen ot' the United States, residing at Jackson, in the county of Jackson and State of Minnesota, have invented certain new and useful Improvements in an End-Gate Construction, of which the following is a speciiication.

rlhis invention relates to improvements in end gates for wagon bodies and has for its principal object to provide an end Vgate which is principally adapted to be usedon wagon bodies in which grain or like is transported, the end gate having an opening therein to permit the dicharge of the grain from the wagon body, a closure being normally disposed over the opening to prevent the grain from accidentally leaking through the opening during the transportation of the grain.

One of the important objects of the present invention is to provide a means for actuating the closure for the opening to permit the raising and lowering of the same in a posit-ive and efficient manner.

A further object is to provide an end gate of the above mentioned character, which is simple in construction, inexpensive,

, strong and durable and furthern'iore adapted lor the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course ot the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of the end gate embodying my invention, and Figure 2 is a sectional view taken approximately on line 22 of Figure 1.

vln the drawing wherein 'for the purpose el' illustration is shown the preferred embodinient oi my invention, the numeral 1 designates the end gate which is supported in the usual manner between the sides of the wagon body 2 at the rear end thereof. The end gate is provided with a substantially rectangular opening in the lower porlion thereof as indicated at 3 whereby the grain in the wagon body may be discharged therefrom in the manner well known in the art.

A closure 4 is provided Jfor the opening 3 and the saine is sldable between the verserial No. 744,019.

tically extending guide strips 5 and 6 secured to the end gate 1 adjacent the respective sides of 'the closure. Extending inwardly from the guide strips 5 and 6 andV secured to the outer faces thereof are the metallic strips 7 and 8 respectively, the same extending Aover the adjacent sides o't the closure 4 for retaining the same in position between the guides 5, and 6 in the, manner more clear y illustrated in Figure 2. Reinforcing metallic strips 9 and 10 are secured to the inner side of the end gate 1 and extends vertically adjacent the side of the opening 3. n

The means for raising and lowering the closure 4 with respect to the opening 3 in the lower portion of the endI gate 1 comprises a pair et levers 11 and 12 respectively which are pivotally secured at their upper ends as at 13 to the upper portion of the end gate 1 on the guide strips 5 and G respectively as clearly illust-rated in Figure 1. A pair of links 14 and 15 respectively are secured at their lower ends as at 16 to the strips 17 and 18 respectively which are secured to the outer side of the closure 4 adjacent the respective sides thereof, The upper'ends of the links 14 and 15 are pivotally secured to the intermediate portions of the levers 11 and 12 respectively g as illustrated at 19 and 20. The lower ends of the levers 11 and 12 provide handles for the purposes to be hereinafter more fully described.

Formed on the lower portion oi' each ot' the links is the lateral extension 21. the outer end of which terminates in the hook 22 for engagement with the lower portion of each of the levers.

lVhen the closure 4 is positioned over the opening 3 so that the grain in the wagon body is prevented ifi-oni being discharged through the opening'. the levers andv links are in the position shown in the full .lines in Figure 1. Vhen it is desired to raise the closure 4 to uncover the opening $3 whereby the grain in the wagon body box may be discharged therethrough, the lowerl ends of the levers are raised upwardly in the direction of the arrows causing the lower portions of the levers to become disengaged-from the respective hooks 22 on the links 14 and 15 and when the levers and A links assume the position shown in the dotted lines in Figure l o the dreWlIlg,

the closure 4 will loe ont of'engagement with the opening 3 and will Yloe disposed in the nl'iperpo'r'tion oi. the en'dgate Whereby the grain maybe discharged through the opening 3. During the upward swinging movement of the ievers,the sidefedg ol the closure will slide along the adjacent side edges of the guides '-anldon the outer side of the end gate.

The closure fl is retnrnedto its 'nori'n'al position over the opening 3. by swinging the free ends of Vthe levers downwardly and when'theflowe'r portions of 'the levers engage'V the5 'hooks 22, the downward swinging movemei'it' of the levers is limited.

5It willthus'be seen Ifrom the-foregoing description, that an end gate'ha-s' been provided wherein the closure for the usual openingprovided'inlthe end gate may he easilyland 'elieientlyoperated, the parts being so arranged -as`to .r render the samel positive in their operation.y

iVlSifile lhave shown the preferred embodiment'ii`my invention, it is to loe understood that various changes inthe size, shape and arrangement ofparts may: loe=resorted to without departing from the spirit of the invention and the scope of the appended claim.

llaving thus *described the rinvention, what claim is zrl`l1e combination with theY end gate of a wagon lied-yi*randhaving an opening in the lower portion thereof, a closure for the opening sl'idable on the end gate, means for raising and lowering the closure comprising -a -pair otlevers pivoted at their upper ends to the end gate on the respective-sides of the closure,a paiiwof links pivotedat their Ilower ends to the `closure adjacent the respective sides of the elosnre, said links being ,pivotally connected to theinterniediate portions of the respective levers., the freeA ends of" the levers providing actuating handles and means for limiting the downward swinging n'iovelnent of' thel levers, saidV means comprising lateral extensions formed onthe'lower portions ofthe links,

the l'free ends' of' the extensionsA terminating in hooks for engagement with 4the lower portions of 'the respective levers.

In'.test1nio1iy whereofl my signature.
